coordinate system 0, 0, 0.) The Axes Indicator allows the user to control the view orientation by selecting

elements of the indicator.

Showing World CSYS Orientation

Planar Rotation - 90°

Change Orientation – Y-Axis

Overlay

Information displayed in the Overlay area is controlled in the Overlay

roll-up group of the Display panel.


Navigation & Selection This section uses a polygon object as an example; all commands in this section work the same for point

and CAD objects except where noted.

Mouse Commands

ACTIVITY: Using the Mouse

Objective

Learn the mouse operations in the Graphics Window.

Pan and Zoom

1. Position the current view by using the Pan command.

Place your cursor in the Graphics Window, press the ALT key and hold down the

right-mouse button (RMB).

Move the mouse right or left to pan from one side to the other. Move the mouse

away or towards you to pan from top to bottom.

Release the right-mouse button (RMB) to stop the pan operation.

2. Change the magnification of the object in the Graphics Window by using the Zoom

command.

Place your cursor in the Graphics Window at a location of interest and use the

scroll-wheel to zoom in by rolling the scroll-wheel towards you. To zoom out, roll

the scroll-wheel away from you.

The Zoom command is sensitive to cursor position, move the cursor and zoom in/out at the area of interest.

3. Cause all objects to Fit within the Graphics Window.

Click the Fit Model to View icon on the Right-Side Toolbar.

View Rotation

1. Place the cursor in the Graphics Window; press and hold the middle-mouse button

(MMB).

Move the mouse in the Graphics Window to rotate the object.

Moving the mouse inside the circle that appears in the Graphics Window performs

a spherical (3D) rotation.

Moving the mouse outside the circle that appears in the Graphics Window

performs a planar rotation, parallel to the current view.


2. The default center of view rotation is the bounding box center of all visible objects. To

change the center of rotation:

In the Graphics Window, right-mouse button (RMB)-click to see the right-click

menu.

Select Set Rotation Center from the right-click menu.

A special cursor will appear for Set Rotation Center.

Left-mouse button (LMB)-click a location on the object in the Graphics Window.

Rotate the object again; notice how the object rotates about the last selected

location point.

If Toggle Dynamic Rotation Center is active in the Right-Side Toolbar, setting the rotation using this method will have no effect.

3. In the Graphics Window, right-mouse button (RMB)-click to see the right-click

menu.

Select Reset Rotation Center from the right-click menu to restore the rotation

center to the center of the visible object(s) bounding box.

Viewing Tools

1. Locate the Predefined Views fly-out on the Right-Side Toolbar and click through

each of the icons on the fly-out to familiarize yourself with both the fly-out behavior

and changing the view orientation.

Predefined Views are orthogonal to the World Coordinate System (World CSYS).

2. The Reset Current View icon when clicked will restore the last predefined view, reset

the rotation center and zoom to view all visible objects.

3. Locate the Shading fly out on the Right-Side Toolbar and click the icons to change

between Smooth Shading and Flat Shading.

Smooth Shading diffuses pixels of the active object causing it to appear smoother than it is. Flat Shading reveals the object as it actually is.

4. The Toggle All Features icon toggles on/off the visibility of all Features in the

Graphics Window. Left-mouse button (LMB)-click the icon several times to

view/hide the Feature object. If there are no available Features, the icon will be

grayed out.

Features are Geomagic objects that have many uses.

5. Fit Model to View will cause all objects to Fit within the Graphics Window.

Fit Model to View will zoom to the extents of all visible objects.

6. Toggle Dynamic Rotation Center will place the center of rotation at the cursor

location each time the left-mouse button (LMB) is clicked on the active object.

This command is activated by clicking the icon and remains on until it is clicked again. When active, the background color of the icon is orange.

again to turn it Off.

This type of selection mode has many uses, including finding areas that are flat for other commands. The smoothness of a polygon object affects how this selection mode works.

This tool is only active on polygon objects.

Figure 15

The majority of commands in the application operate using the following selection syntax:

If nothing is selected when a command is activated; the command will affect the entire active

object or all active objects.

If a selection is present when a command is activated; the command will affect the selected

area only.

End of Activity

End of Activity


Dialogs Geomagic dialogs have several controls in common with each other; this section describes the most

commonly used controls and conventions. The majority of Geomagic commands are dialog based.

OK button; accepts any changes made while in the dialog and exits the dialog.

Cancel button; discards any changes made while in the dialog and exits the dialog.

Apply button; updates the command to any changes made while in the dialog – this is

useful to preview parameter/option changes while making adjustments, without

committing to the current settings.

If an Apply button is present in a dialog, you must press it to activate the command.

Next button; Analogous to OK and restarting the command.

Reset button; resets dialog parameters to defaults; equivalent to restarting command.

Slider Control; when scrolled to the right, increases parameter

affected.

Roll-Up Groups; when rolled up, an arrow in the group title points downward, see Figure 18. Clicking

anywhere on a rolled up group title will expand the group and reveal additional dialog elements, values,

inputs or activate extended commands, see Figure 19.

on the tree; if the object has branch nodes they will

also be copied. Useful for creating duplicates for

alternative workflows or a backup object.

Pin/Ignore; Used only for Global Registration

command. Pin will constrain the location of the

selected object. Ignore is useful when a one or more

of scans are in a group and you do not want them

used in Global Registration command.

Create Group creates a folder object on the Model

Manager Panel tree that can be used to store objects

of the same data type.

Properties… displays the properties of the selected

object, useful when a Feature object is selected.


Graphics Window Context Menu

With no selection made in the Graphics Window a

context menu of commonly used view and selection

commands are available.

Default right-click menu shown.

With a selection made in the Graphics Window a

context menu with data sensitive shortcuts is added to

the top of the context menu.

Polygon context menu shown.

Search

The Search Box at the top right corner of the application builds a ribbon based on what is

typed into the box. The example in Figure 20 shows the word “line” typed into the Search Box

and the ribbon that is dynamically created with commands that contain the text string.

Figure 20

Clicking the “X” in the Search Box will remove the search ribbon and restore the previous

ribbons.


Help

Help Dialog

Pressing the F1 key will open a help dialog that contains and Contents, Index and Search

commands.

Context Sensitive Help

Placing the cursor over any icon and pressing the F1 key will invoke help for that command.

When a dialog is active; placing the cursor anywhere in the dialog and pressing F1 will invoke

help for the command active in the dialog.


Data Types The application supports several data types including collected point data, polygon data and CAD data.

Point clouds are common data types which consist of individual point locations. The application can

import several hardware device native file formats and also provides plug-ins for several hardware

devices, enabling direct input of scan data into the application.

Unordered Point Data

Unordered or raw point data is a collection of points, each having an X, Y, Z location. When

viewed up close, unordered point data is semi-transparent.

Unordered data may contain normal/vector information or not, point data which contains no

normal information will be black in color, as shown in Figure 21. The same point data after shading

is shown in Figure 22.

Shading point data enables a better view of the shape. When point data is shaded, the default

color becomes light green in color.

Data collected using a hardware plug-in is automatically shaded.

Shading can be applied to an unshaded point object in one of two ways:

Points > Repair > Shading > Shade Points

Points > Repair > Shading > Repair Normals

Identifies a scan object in the Model Manager Panel as unordered point data.

Figure 21 - Unshaded Point Data

Figure 22 - Shaded Point Data

When using Repair Normals for the first time on an unshaded object, you may be presented with a continuation dialog box – this dialog should be answered ‘Yes’ if encountered to allow access to the entire command.


Ordered Point Data

Ordered point data is averaged into a cell/grid format and does not contain as many points as

unordered point data.

Unlike unordered point data, you cannot see through a point cloud of ordered point data

because of the cell structure.

Ordered data point spacing is always uniform with a grid like structure and is also green in color

when viewed in the application.

Ordered point data has a different set of point tools than unordered point data.

When multiple ordered data scans are combined into a single point object, the result is an

unordered point cloud.

Identifies an object in the Model Manager Panel as ordered point data.

Figure 23 – Ordered (Cell) Point Data

Figure 24 – Cells with Points Displayed


Polygon Data

Polygon data is sometimes referred to as a mesh; triangles are formed by linking point data that result in a

mesh. Polygon data comes from a variety of sources that include modeling software, scanning devices

and a result of wrapping points in Geomagic.

When a polygonal object is generated the normal faces are colored blue by default, the back

face or opposite side of the normal face is colored yellow.

If the mesh of a polygon object is modified, the underlying point structure will likewise be modified.

In the event that any polygon object normals are inverted either from other software or from the

wrapping process in Geomagic, use Polygons > Repair > Repair Tools > Flip Normals on the ribbon

to reverse the orientation of normals.

Identifies an object in the Model Manager Panel as polygon data.

Figure 25 – Polygon Object Normals Correct

Figure 26 – Polygon Object Normals Inverted

Clicking the Display Panel tab and toggling on Edges in the Geometry Display roll-up group will reveal the

mesh construct of any polygon object.

A polygon object can also be changed into the point object.

Polygons > Convert > Convert to Points on the ribbon changes a polygon object into a

unordered point object.


CAD Data

CAD data is a collection of faces or bounded surfaces typically created in engineering design software.

CAD data occurs by:

Opening/Importing external CAD files, typically IGES or STEP neutral file exchange formats

Directly opening or importing supported native CAD file formats

CAD data is gold in color when activated and displays CAD face boundaries

A CAD object may be down converted to a polygon object.

Identifies an object in the Model Manager Panel as CAD data.

Figure 27 – CAD Data

Changing a CAD object into a polygon object will cause all CAD face boundaries to become

boundaries and intersections to become subdivision points. Use the Polygons > Boundaries > Remove

commands on the ribbon to remove these elements if desired.


Free Curve Data

Free Curve data is analogous to wireframe geometry and can be extracted through a section from a

polygon or CAD model.

Curve data has many properties:

Curves may be defined by a section cut.

Free Curves can be converted to points and used for either deviation analysis or as a location set.

Free Curves may be saved in IGES format.

Identifies an object in the Model Manager Panel as 3D Curve data.

Figure 28 – Curves

Figure 29 – Used for Deviation Analysis


Data Handling

The first step in the inspection process is to load the necessary data files. You can inspect any

combination of data types, including point clouds, polygon (STL), and CAD models.

The Model Manager Panel uses a REF (reference) and a TEST (test) label for all comparison models. A

REF label can be assigned to either a Polygon object or CAD object (preferred). A TEST label can be

assigned to a point object, polygon object or another CAD object.

Figure 30

Many scanner formats are supported; this allows for fast and easy direct import of native binary file

formats.

A typical inspection would involve comparing scan data of the manufactured part to the engineering

CAD model. A CAD model is imported via neutral file format (IGES/STEP) or direct import of native CAD

file from supported applications.

Some point cloud and polygon formats might require you to specify the units that the data was

scanned in, such as millimeters or inches.

When opening or importing a CAD model; the application automatically assigns a REF label. When

opening/importing a point model or scanning directly, the application automatically assigns a TEST

label. In both cases; the current REF and TEST may be cleared or re-assigned to other models if so

desired, through the Model Manager Panel context menu. An STL or OBJ file when opened/imported is

not assigned either a REF or TEST and needs to be assigned a label in the Model Manager Panel.

The TEST object is the one that will be moved to the REFERENCE object during the alignment process,

and the REFERENCE object will in turn be used to generate the RESULT object. The REFERENCE object is

also used to store Automation.


Scan Registration

Overview

The process of registration provides the ability to align scans with different coordinate systems.

Manual Registration (1-Point)

One point registration allows the user to align multiple scan objects using a single pick location that is

common between the Fixed and the Float views in the same view orientation.

ACTIVITY: Scan Registration (Unordered Point Data)

Objective

In this activity you will align scans of unordered point objects using Manual Registration, refine the

alignment using Global Registration and combine the individual scans into a single object for more

processing. The scan data used in this activity is typical of raw (unordered) point data scans of a part

scanned in different set-ups.

Commands

Manual Registration

is opened. If they are not active, make them

active by CTRL+LMB clicking them in the

Model Manager Panel.

Figure 31

2. Click Alignment > Scan Registration > Manual Registration on the ribbon to start

the Manual Registration command.

The Graphics Window will be divided into 3 view ports. The upper left view port is the Fixed view port and the upper right view port is the Floating view port. The wide frame at the bottom serves as a preview after registering the object in the Floating view port to the object in the Fixed view port.

3. Select the 1-Point Registration radio button in the Mode roll-up group if it is not

already active.


4. Define Fixed and Floating objects to align.

From the Fixed list in the Define Sets roll-up group, select Scan 001. The selected

scan will turn red and appear in the Fixed view port (top left view).

From the Floating list in the Define Sets roll-up group, select Scan 002. The

selected scan will turn green and appear in the Floating view port. (top right view)

The Fixed and Floating objects selected in the lists will appear in the Fixed and Floating frames similar to Figure 32 .

There are two sides to each scan; always make sure you rotate the dark red and bright green sides of the scans towards you for registration.

Figure 32

5. Orient Fixed and Floating views for selection.

Rotate each of the scans to the positions shown in Figure 33.

It is important that the Fixed and Floating view orientations be as close as possible to each other when using 1-Point Registration (default), otherwise the registration may not work correctly.

Figure 33


6. Pick a common point that is available in both the Fixed (red) and Floating (green)

view ports, see Figure 34.

If you accidentally pick the wrong point, use the CTRL+Z keys to undo the last selection.

Figure 34

7. When using 1-Point Registration; registration

will start automatically when the second point is

picked. If you have performed a successful

registration the bottom window will update to

show the aligned scans with overlapping data as

shown in Figure 35.

Press the Register button to help refine the

registration of the current scan.

If the scans are poorly aligned; either the view orientations were not close enough or you did not select registration points near enough to each other and need to try again. If this is the case, click the Unregister button in the dialog to move the scans back to their original positions and start the process again

Figure 35

8. When satisfied with your registration, accept the current registration and place the two

scans into a group object if there is a checkmark in the Add to Group checkbox.

Click the Next button to accept the current registration.

In this example, you will have a checkmark in the Add to Group checkbox and use the default name of Group 1.

Click OK to exit the dialog.

9. You will notice in the Model Manager Panel that both scans have been placed in

Group 1.


Global Registration

1. Refine the registration (alignment) between the scan objects.

Click Alignment > Scan Registration > Global Registration on the ribbon.

Click Apply to start the registration process.

The registration process will stop when either convergence is detected or the maximum number of iterations has been reached.

2. After reviewing, click OK to accept the registration and exit the dialog.

Combine Point Objects (Unordered Point Data)

1. After registration, the scans are aligned but are still separate and need to be combined

into a single point object. Verify that all scans are in a single Group in the Model

Manager Panel and that Group is active.

Click Points > Combine > Combine Point Objects on the ribbon.

Name the point object to be created by typing “Model” in the Name field.

Accept the remaining default settings.

Click Apply.


The point object is now ready for further processing.

End of Activity


Registering Ordered Scan Data

Ordered scan data contains cells, and depending on the scan angle, some cell data may be inaccurate

and should be filtered out. The registration of ordered data scans is identical to that of unordered data

but there are a few options when handling ordered data that will be covered in the next activity.

ACTIVITY: Scan Registration (Ordered Point Data)

Objective

Align multiple, overlapping scans captured at different positions using the Manual Registration command.

Refine the alignment using Global Registration and combine the individual scans into a single point

object. Here is an overview of the steps to create a point object from unaligned ordered data scans:

Filter out poor cell data per scan that was collected using a poor capture angle.

Roughly align the scans to place them in the same orientation using manual registration.

Perform global registration to minimize the deviation between scans.

Remove overlapping cell data and combine the scans into a single point cloud for more

processing.

Commands

Filter

Manual Registration

from the Tasks list.

Use the Open Files dialog to navigate to the

training files folder. Select TR-02.wrp in the

Open Files dialog.

Click OK to open the file.

These scans were taken with a scanner which outputs ordered data, meaning the point cloud is formatted in a grid-like arrangement.

Figure 36


2. If all scan objects are not all highlighted at this

time… highlight all of the scans in the Model

Manager Panel by holding the CTRL key while

LMB selecting each of them.

You can also perform a range selection by selecting the first object in the range, pressing the Shift key and selecting the last object on the range.

Figure 37

Filter Points

1. Remove cells whose normals are more than a specified degree from the scan direction.

Click Points > Repair > Filter on the ribbon.

Enter 72.0 into the Angle field.

Click Apply to start filter of data.

Click OK.

This command is only available when working with ordered (cell) data.

Delete Stray Scan Data

2. Automatically detect and remove small, undesired portions of the scan object.

Click Select > Data > Select By > Area on the ribbon.

In the dialog that appears, enter 2.0 in the Percent box.

Click Apply.

Several of the small segments will get selected. This command selects pieces of the scan that contain less than the specified percentage of that scan’s total area.

Click OK.

3. The small segments are still selected so press the DEL key to remove them from the

scan object.

4. Now that the data has been filtered and edited, you can begin to align the scans. To

align these six scans, first make sure they are selected in the Model Manager Panel.

Select Scan 001, press the Shift key and select Scan 006 to specify a range

selection which will also activate the selected objects in the Model Manager Panel.


Manual Registration (n-Point)

1. Click Alignment > Scan Registration > Manual Registration on the ribbon. This

command allows you to roughly align multiple scans by picking areas where two scans

overlap.

2. Select the n-Point Registration radio button in the Mode roll-up group.

3. Define Fixed and Floating objects to align.

From the Fixed list in the Define Sets roll-up

group, select Scan 001. The selected scan will

turn red and appear in the Fixed view port. (top

left view)

From the Floating list in the Define Sets

group, choose Scan 002. The selected scan will

turn green and appear in the Floating view

port. (upper right view)

The Fixed and Floating objects selected in the lists will appear in the Fixed and Floating frames similar to Figure 38 .

There are two sides to each scan; always make sure you rotate the dark red and bright green sides of the scans towards you for registration.

Figure 38

4. n-Point Registration does not require exact view orientation like 1-Point

Registration does. n-Point Registration also requires a minimum of 3 points picked

in each view.

Rotate each of the scans to positions similar to Figure 39 to see most of the

overlapping data.

Figure 39


5. Pick the points as indicated in Figure 40 on both the Fixed (red) and Floating scans

(green) at approximately the same locations on each.

If you accidentally pick the wrong location, press CTRL+Z to undo the last selection.

Figure 40

6. A quick orientation of the scan data is

done based on the points selected.

Click the Register button to start the

registration process.

View the fitting of the 2 scans as shown

in Figure 41.

If the two scans do not appear to be properly aligned but are pretty close, try clicking the Register button again to refine the fit.

If the scans still do not align, click the Unregister button to start again.

Figure 41

7. When satisfied with your registration, click the Next button. This will accept the current

registration and place the two scans into a group object if there is a checkmark in the

Add to Group checkbox.

In this example, you will have a checkmark in the Add to Group checkbox and use

the default name of Group 1.

You will notice that Group 1 is automatically created and highlighted in the Fixed list

after clicking the Next button.

As each Floating scan is registered, it will be removed from the Floating list and be

placed in Group 1.


8. Leave Group 1 selected in the Fixed list and click Scan 003 in the Floating list to

start the registration of the next scan.

Rotate the views as necessary to find the overlapping locations to make a selection

on.

Select approximately the same 3 points in each view port.

Click the Register button.

9. Click Next after successfully registering this scan to add Scan 003 to Group 1.

10. Continue the previous process and register

the remaining scans from the Floating list

until all are aligned.

You will continue to rotate the views to

locate and use the overlapping areas of the

scans to register the remaining scans.

Once you have registered the last scan in

the Floating list, all scans will be visible

again.


Figure 42

11. Look at the Model Manager Panel and you will notice that all scans have been placed

into a Group.

Global Registration

1. Refine the registration (alignment) between the scan objects.

Click Alignment > Scan Registration > Global Registration on the ribbon.

Click Apply to start the registration process.

Several iterations of an alignment algorithm are run to better align the scans. Statistics will be reported in the dialog after each scan so the user knows the status of the current alignment.

The operation will terminate when one of three things happen:

o The number of maximum iterations is performed.

o A specified number of iterations are run without convergence.

o When the command stops, the system will display the two scans with the greatest deviation in the Statistics group.

Hitting the ESC key at any time during the calculation will stop the command after the current iteration.


2. Analyze the overlapping scan data to see how

well the registration worked.

Click the Analysis icon in the Operations

roll-up group.

Set the Density value to Full.

Click Compute.

Once the system is done processing, a colorized deviation map will display how each scan is related to its neighbor.

To speed the process up, set the Density value to something other than Full.

This is useful in reviewing the scans to see if one of the scans is causing the rest to be out of alignment. If so, then you can remove the errant scan from the group of scans and run the Global Registration again.

Figure 43

3. Review each scan.

Select the Single Object radio button, and then use the arrow buttons to cycle

through each scan

After reviewing each scan, click OK to accept the registration.

Combine Point Objects (Ordered Point Data)

1. After registration, the scans are aligned but still separate and need to be combined

into a single point object. Verify that all scans are in a single Group in the Model

Manager Panel and that Group is active.

Click to Points > Combine > Combine Point Objects on the ribbon.

Name point object to be created by typing “Model” in the Name field.

Check the Remove Overlap checkbox; this will remove overlapping scan data from

the Ordered Data objects. This setting only applies to ordered data.

Notice the number of cells in the Overlay area of the Graphics Window.

Click Apply.

Click OK; the combined point object is created in the Model Manager Panel and

the Group of scan objects has been deleted from the Model Manager Panel.

2. Remember that the source data for creating the combined point object was Ordered

Data. Notice that the newly created combined point object is Unordered Data.

The new point object is now ready for further processing.

This is a good place to save your work in a typical workflow.

Detect Sphere Targets


Notice there are 3 tooling balls of the same size attached to the part. Some portion of each tooling ball is captured in each scan, see Figure 44.

As with other types of registration, the scans used in the registration process must

be selected in the Model Manager Panel. If any of the scan are not selected, select

them now in the Model Manager Panel.

A minimum of three spheres of equal size must be used to triangle the target points correctly.

Figure 44

2. Click Alignment > Scan Registration > Detect Sphere Targets on the ribbon.

There is a short pause upon entering the command as it initializes.


3. Define on the scan data the data that

represents one of the tooling balls.

Use any selection tool to select the

scanned data of one of the tooling

balls as shown in Figure 45.

In the Selection Parameters roll-up

group, click the Set Selection

Parameters button.

All point data that matches the spherical curvature specified will be highlighted.

Curvature data selected can be refined using the Max/Min Curvature sliders in the Selection Parameters group.

Figure 45

4. Click Apply; the view will change to

display the proposed matching spheres

between scans, see Figure 46.

The colorized data is called Coherence and may be refined using the Coherence slider if not correct.

Target Cleanup (optional)

1. After registration, the spherical data and targets can be removed if you desired at this

time.

Click Alignment > Scan Registration > Target Cleanup on the ribbon.

Click OK to remove the spherical scan data and the target points defined in Detect

Sphere Targets.

You can choose to keep the target points by checking on Keep Target Points.

The spherical scan data will be removed and holes in the scan will result from where the tooling balls were attached, see Figure 49.

Figure 49



1. After registration, the scans are aligned but are still separate and need to be combined

into a single point object. Verify that all scans are selected in the Model Manager

Panel.

Click to Points > Combine > Combine Point Objects on the ribbon.

Name the point object to be created by typing “Model” in the Name field.

Accept the remaining default settings.

Click Apply.


2. The point object is now ready for further processing.

End of Activity


Points

Overview

While a point object is active you have the opportunity to improve the scanned data. Noisy data can be

improved, and point sampling techniques can be employed to reduce the density of point cloud data.

All cleanup procedures are optional, but a “cleaned” point object can be converted to a polygon

object with greater efficiency and higher quality. Sampling point objects also improves the computation

times of other commands; it is very easy to capture more data than is necessary when scanning a part,

more point data is not always “better”.

Commands covered in this section include the following:

Select > Disconnected Components

Select > Outliers

Reduce Noise

Uniform Sample

Wrap

2. Change view to a previously saved user defined

view.

3. In the Graphics Window, RMB click.

Select User-Defined Views > QuickView 1

from the right-click menu to restore the view

shown in Figure 50.

User-Defined Views can save any view orientation and are instantly available on the right-click menu as they are saved.

Figure 50


Disconnected Components

1. Scanned data often includes points that are isolated from the main point cloud; these

types of points are referred to as disconnected components. You will now select these

isolated points.

Click Points > Repair > Select > Disconnected Components on the ribbon.

Set the Separation parameter to Low; observe the number of points selected in

the Overlay.

Set the Separation parameter to High; observe the number of points selected in

the Overlay.

Set the Separation parameter back to Low.

A Low setting uses the smallest space between points that will find the most isolated points. The Medium and High settings will find fewer points as the size of the space between isolated points is increased.

2. Click OK to exit the dialog; the points detected remain selected.

3. Press the DEL key to remove the selected (isolated) points.

Outliers

1. Outlier detection is based on a point to point relationship. The Select > Outliers

command analyzes each point for proximity to neighboring points based on a

sensitivity parameter, as sensitivity increases more outliers are detected and vice

versa

Click Points > Repair > Select > Outliers on the ribbon.

Click the Apply button to analyze the point object.

2. Change view orientation to review select points.

Also notice the number of points selected in the

Overlay, see Figure 51.

Rotate the point object and Zoom in/out to

observe the points selected in the Graphics

Window.

Figure 51

3. Adjust Sensitivity parameter to see how it impacts the number of points selected.

Change the Sensitivity to 80 and click Apply. Review Overlay information; notice

the Selected Points value is lower.

Change the Sensitivity back to 85 and click Apply.


5. Press the DEL key to remove the selected (outlying) points.


6. It is not required to clean all outliers; however, it is good practice is to run this

command a few times to get the most outlying points removed from the point object.

Click Points > Repair > Select > Outliers on the ribbon.

Use a Sensitivity value of 85.

Click Apply. Notice that fewer outliers have been detected the second time. Each

time Select Outliers is used with the same Sensitivity value, fewer outliers will be

selected.


8. Press the DEL key to remove the selected (outlying) points.

The Select Outliers and Delete commands are usually run in tandem, which makes them a good candidate for a Macro.

Manual Editing

1. Zoom, pan and rotate as necessary to locate and manually delete any remaining

stray points that may exist around the part perimeter.

See Figure 52 for an example of stray/errant points.

Try using different selection tools from the Right-Side Toolbar.

Remember that CTRL+LMB when using the selection tools, deselects.

Figure 52

2. After selecting stray points, press the DEL key.

3. Continue to rotate, zoom, manually select and delete until you are satisfied that

only points that describe the scanned part remain.


Reduce Noise - Optional

Reduce Noise is a powerful tool when used properly; if used improperly, it may introduce distortion into a scanned part. This command should NOT be used on the TEST data.

1. Click Points > Repair > Reduce Noise on the ribbon.

Noise Reduction is a form of compression that moves points closer together resulting in a smoother polygon object when the points are wrapped.

2. Rotate to the view shown in Figure 53.

Using the defaults.

Click the Apply button.

Observe the information in the Statistics roll-up group. Staying alert to the Statistics roll-up group will help with assessing how much distortion is acceptable.

Figure 53

3. Click on the Preview roll-up group title to expand and activate the Preview

command.

The cursor will change to a cross-hair shape. Click near the location shown in

Figure 54.

A polygon preview will be rendered at the area selected as shown in Figure 55.

Zoom in to view the preview in greater detail.

Figure 54

Figure 55


4. With the Preview roll-up group still expanded, move the Smoothness slider control

in the Parameters roll-up group to a value of 2. As you move the slider, the preview

will dynamically update to reflect your changes.

5. With the Preview roll-up group still expanded, change the reduction type in the

Parameters roll-up group to Prismatic Shapes (Conservative) and observe how

the preview changes.

Click the Preview roll-up group to collapse the group and deactivate the preview.

Rotate and Zoom to one or two other locations on the object and at each location;

expand, select an area, preview that area and collapse the Preview roll-up group to

deactivate it.

If the Preview roll-up group is still expanded and active, collapse the Preview roll-

up group at this time to deactivate it.

6. Click Apply to apply the previewed changes to the entire object.

Note changes of Maximum Distance in the Statistics roll-up group. If this were a high precision part, the amount of noise reduction applied may distort the scan data beyond the tolerance zone of the part.

7. In the Parameters group, enter a value of 0.5mm in the Deviation Limit field.

Click Apply; the scan will be updated with a limit on how far points can move.

Observe the Statistics roll-up group again; the Maximum Distance of any point moved will not exceed the value set in the Deviation Limit field.

Use the Deviation Limit parameter to limit the movement of scanned data.

8. Click on the Display Deviations roll-up group to expand and activate the Display

Deviations command.

The display will change to a deviation map with a spectrum bar, see Figure 56.

Find the Max. Critical input field and change the value to 0.1 mm. Press the Enter

key, the Min. Critical will automatically update to the inverse value.

Find the Max. Nominal input field and change the value to 0.01 mm. Press the

Enter key, the Min. Nominal will automatically update to the inverse value.

The display will update the deviation color map and the spectrum bar, see Figure 57.

Figure 56

Figure 57


9. Click OK to exit the dialog.

Reduce Noise is not recommended for processing scanned objects to be used as TEST objects in Geomagic Qualify. The exception would be to create a REF object for Geomagic Qualify. When creating a reference object, great care should be taken as this command can introduce distortion that could lead to inaccurate results in Geomagic Qualify.

Point Sampling

1. Change the density of the point cloud without moving any points.

Click Points > Sample > Uniform on the ribbon.

Select the Absolute radio button in the Input roll-up group.

Sampling changes the density of a point cloud without moving any points.

2. Orient view in order to see how sampling

affects the point cloud.

Rotate and Zoom close to your point

object, similar to Figure 58.

Note the current number of points in

the Overlay.

Click Apply.

Note the change in the Overlay and

the new density of the point object.

The default sample of Absolute is typically a 45% to 65% reduction of points based on existing density of the point cloud.

Figure 58

3. Adjust spacing parameter.

In the Input roll-up group, select the Define Spacing by Target radio button.

Change the value in the Points field to 80000. This sets a target of approximately

80,000 points for the sample.

Click Apply and note the change in the Overlay and the new density of the point

object.


The sampled point object is now ready for other operations.

It is possible to over-sample a point cloud; ideally you want to improve the performance of a point cloud while maintaining its shape description.


Wrap - Optional

1. Convert point object to a polygon mesh (STL) object.

Click Points > Wrap > Wrap on the ribbon.

You have already performed a managed noise reduction, locate Noise Reduction in

the Settings roll-up group and set the drop-down list to None.

The Wrap command creates triangular faces by “connecting the dots” of a point cloud. The quality of a “wrapped” point object is dependent on the quality of the data it is derived from. Wrapping an unordered point object will produce approximately twice the number of triangles as there are points. The triangles in a polygon object are commonly referred to as a “mesh”.

2. Click OK to begin the Wrap operation.

When Wrap is applied to ordered point data; no dialog will appear – the point cloud will be wrapped automatically.

3. A polygon object is created and the point object it was created from remains in the


Figure 59

End of Activity


Polygon Objects

Overview

A polygon model or mesh is a collection of triangles; vertices are where these triangles meet, and the

vertices are the same as the underlying point object. If the polygon structure changes, so does the

underlying point structure.

An STL file type is synonymous with a polygon model; they are one and the same. Many applications can

produce STL files that can be imported to for inspection processing. Several hardware scanner vendors

also produce an STL file as a means of file sharing with external applications.

This section is designed to introduce you to commonly used commands that improve the quality of a

polygon object.

Alert: Creating triangles or modifying them disconnects from the original scanned data for inspection purposes. The steps outlined in this section should not be used to modify a TEST object as smoothing or creation of triangles does not reflect what was originally scanned.

Filling Holes

Hole filling creates data structure not present in a scanned inspection model; exercise caution when using this command with inspection data.

1. There are two ways to fill holes, Fill All and Fill Single. Fill All finds all boundaries

and does as the name implies. Fill Single interacts with each hole; you can also

change either/both the Technique and Mode as desired in Fill Single mode.

Fill Techniques control the curvature of a fill.

Curvature filling starts tangent to edges and ends tangent based on curve projection.

Tangent filling starts tangent to edges and projects a flattened curve.

Flat filling is as the name indicates.

Fill Modes control the way a hole fill occurs.

Complete fills a closed boundary.

Partial fills between two selected points and an included boundary.

Bridge fills from selected triangles edges to selected triangle edges.

Feature Objects

Overview

Features are 2D and 3D geometric objects created in the application. A feature object contains

properties and can be “best fit” to polygon objects by applying them to selected regions. Feature

objects can be used for a variety of commands, such as;

Alignment

GD&T

3D Dimensioning

Sectioning for 2D Compare and 2D Dimensioning

Any feature may be edited, re-created from an edited selection set, deleted, and any feature property

may be examined. Feature visibility may also be controlled and features may be renamed in the Model

Manager Panel after creation.

Features can be created on the Reference (REF) object or the Test (TEST) object. If creating features on

the REF object, you can have the application create the features on the TEST object automatically if

there is enough scan data available.

Features can also be created on the TEST object during the capture process if there is a hard probe

available. This is done with Capture > Collect > Probe Features commands.

It is important to define all features that might be required during the inspection process as early as possible.

Auto Create Features

1. Click Features > Create > AutoCreate or click the Home > Features >

AutoCreate.

This command will try to automatically reconstruct all green REF features on to the TEST object. Features that are green are considered to have enough creation information that the system should be able to extract the same information from the TEST object. If the feature is orange, then it is considered non-automatable as there is not enough information available to be extracted from the TEST in order to re-create.


2. Automatically build all green REF object features on the TEST object.

Place a checkmark in the Perform Correspondence Alignment (Best-Fit)

checkbox.

Click Apply.

After clicking Apply, the command will perform a temporary best fit alignment so that each point in the TEST object will get mapped to a CAD face which the point represents. After the alignment and mapping is completed, the features will be created on the TEST object using the mapping (correspondence) for the fitting of the features.

Notice that Plane 2 (created via Through Axis) was not created on the TEST object as it was orange on the REF object. This feature was created with a manual pick on the CAD face boundary which does not exist on the TEST object; therefore it cannot be recreated on the TEST object.

Click OK.

Alignment

Overview

After loading the data sets, it is often necessary to align the TEST object to the REFERENCE object. The

method chosen for alignment will have an impact on the analysis, so it is important to select the

alignment method most suitable for the type of inspection being performed. There are several types of

alignment techniques that can be used to register a TEST object to a REFERENCE object:

Best Fit Alignment Requires no user-defined features; the software

calculates the best fit between the two objects

automatically; great for organic, free form shapes

Feature-Based Alignment Uses a series of user-defined planes, axes, points,

cylinders, slots, holes, faces, and edges; these

features are then matched or paired to perform the

alignment; great for mechanical, prismatic shapes.

RPS Alignment Reference Point System

Allow you to constrain certain features in specific

directions, in order to replicate a real-world fixture.

Combination Feature-

Based and Best Fit

You define one or two features, then allow the

software to best fit to constrain the remaining

degrees of freedom.

Once the two objects are aligned, the analysis phase begins. A transformation matrix can also be

exported for use with future parts.

ACTIVITY: Best Fit Alignment

Objective

Perform a Best-Fit Alignment.

Best Fit Alignment

1. Perform alignment of object using the Best Fit command.

Click Alignment > Object Alignment > Best Fit Alignment or click the Home >

Alignment > Best Fit Alignment

When the dialog is displayed, the default Sample Size value is 300. This means the command will use 300 randomly selected points to get an initial orientation. After the first pass, the Sample Size will automatically increase to 1500 and Fine Adjustments Only will be activated to achieve the final alignment to the specified Tolerance.

Click Apply to start the alignment process.

The Deviator Elimination parameter is available for parts that have known imperfections that may reduce the alignment accuracy. With this parameter enabled, the system ignores points that deviate significantly from the reference model after the initial rough alignment. The Deviator Elimination slider determines the deviation threshold for points to be ignored.

Figure 114

2. When the alignment is complete the Statistics roll-up group will list the Avg. Error

between the two objects. To refine the fit, you can adjust the Deviator Elimination

slider to have the command ignore points that has the largest deviation during a re-

fit.

After adjusting the slider, click Apply to restart the calculation. The Statistics will

update accordingly.

Click OK to accept the alignment and exit the dialog

End of Activity


ACTIVITY: Selected Best Fit

Objective

The Best Fit Alignment command also supports user selections for specific fitting. Pre-selecting geometry

on both the REF and TEST objects instructs the Best Fit Alignment command to fit only these pre-selected

areas.

Manage Correspondence

1. Click Tools > Manage >

Correspondence to view the mapping of

TEST object data to REF object faces. On

this model, this was automatically

generated by the AutoCreate command.

This “mapping” is known as

Correspondence. Figure 119.

Editing of Correspondence should be limited. The information provided in this section is solely for demonstrative purposes.

For example, the region of TEST data that is colored green is mapped to a REF object face that is also colored green. This mapping is used when auto creating the features on the TEST object. The black points were not mapped, so they were placed on the Clipboard.

Figure 119

2. Click View > Navigation > Zoom >

Zoom In to window the area shown in

Figure 120.

Figure 120

3. Select the blue region which represents

the radius of the part shown in Figure

121. This selected region represents all of

the scan points mapped to the CAD face

which represents the radius. This data

was used to create the Cylinder 1

feature.

The black points represent unmapped data placed on the Clipboard, data on the clipboard is not used in feature creation or the GD&T command. To hide this data, remove the checkmark from the Clipboard checkbox in the Display roll-up group.

Figure 121

4. Click the Delete button in the Manage Correspondence roll-up group.

Deleting correspondence will remove all features created on the TEST object.



5. Click to Application Button > Options… to define a global shrinkage (setback)

value which will be used during the generation of new correspondence.

Click Miscellaneous under Operations and locate the Correspondence

Shrinkage group box, Figure 122.

The settings in this group box are used during the creation of the Correspondence. This will allow you to rollback all edges on the object when correspondence is created. This will help reduce the need to edit the correspondence and possibly lose defined features or fail later during automation.

Figure 122

6. Select the Relative % radio button and change the value to 5.0.

A Distance setback from all edges is also available. The Maintain Slot Boundary checkbox will keep shrinkage from occurring around slots or holes if checked.

Click OK.

The Shrinkage values are maintained across sessions, it is recommended after adjusting the Shrinkage value for an objects correspondence, the values should be set back to zero.

To recreate the correspondence using the new Shrinkage value, click Features >

Create > AutoCreate or click Home > Features > AutoCreate.

Change the Max. Deviation setting to 0.05 in.

Click Apply to create features on the TEST object.


7. Click Tools > Manage > Correspondence to view the new correspondence

generated by the AutoCreate command.

8. Reorient the view of model as shown in Figure 123.

Remove the checkmark from the Clipboard checkbox if checked.

Remove the checkmark from the Reference checkbox if checked.

You will notice that the TEST object data is now rolled back from the edge of the model.

Figure 123 and Figure 124 show the difference between not having and having shrink applied to the correspondence.


Figure 123 - No Shrinkage

Figure 124 - 3% Shrinkage

9. Click on other faces and examine how correspondence shrinkage has affected all

faces of the TEST object data. When additional feature creation occurs or other

analysis, this correspondence will be used.

10. To display data that will not be used in downstream commands.

Remove the checkmark from the Test checkbox in the Display roll-up group.

Place a checkmark in the Clipboard checkbox in the Display roll-up group.

This will display the TEST object data that has been excluded from the current correspondence through Shrinkage; the excluded data is placed on the Clipboard to be ignored in all future computations involving correspondence.

RPS Alignment

ACTIVITY: RPS Alignment

Objective

Perform a Reference Point System (RPS) Alignment.

RPS Alignment allows you to constrain certain features in specific directions, in order to replicate a real-

world fixture. RPS Alignment provide for an iterative alignment instead of a fixed feature alignment,

special features know as Line Targets and Point Targets are used to provide this flexibility.

Analysis – 3D Tools

Overview

The application offers many ways in which to quantify the resulting deviations between a REF and TEST

object. 3D Compare is a graphical depiction of the deviations between the two objects and is created in

the form of a RESULT object.

A RESULT object is a copy of the REF object that is comprised of many colored blocks. The TEST points are

projected onto the surface of the RESULT and the magnitude of their deviation is displayed as a color in

the Spectrum Bar.

You can query specific points on the RESULT using the Create Annotations command. These annotations,

or flags, display the deviations between TEST and REF objects, at specified coordinates on the RESULT

object. Points can be created manually created or automatically using a set of saved coordinate points,

known as a Location Set.

Figure 136 – Sample 3D Compare Deviation Analysis

Once you have created a RESULT object with the 3D Compare command other analysis commands

become available.

The Compare Boundary command allows you to compare the edges of the part, which is especially

useful in the inspection of sheet metal parts. Problems such as spring-back and trimming errors are easily

identified using this command. Like the RESULT object, the boundary view objects allow for annotations to

be defined.

The Compare Features command allows for a one-button comparison of features. The command will

generate annotations with the information on the compared features. This can be done automatically or

manually.

The Annotate Features command will allow you to extract feature information if you only have scan data

available unlike the Compare Feature command which requires both a REF and TEST object. This is very

handy for users with scanner that have hard probe capabilities.


3D Compare

ACTIVITY: 3D Compare

Objective

Create a color deviation map between the REF and TEST objects and generate annotations to highlight

specific areas of deviation. Also create a location set and export a location set.

3. The Deviation Spectrum is interactive, adjustments to the values changes the

Graphics Window display.

Color Averaging can be adjusted via the slider. This allows you to control the amount of influence any single point will have on the result display. The Low setting causes the color depicting the deviation for each point to be localized near the point (Figure 139). High setting allows the colors from neighboring points to blend, resulting in a more continuous color plot (Figure 140).

Figure 139

Figure 140

By adjusting the settings under the Display roll-up group, you can change the appearance of the RESULT object in Graphics Window.

By placing a checkmark in the Test Object checkbox, you will turn on the display of the TEST object points. This can be helpful in the interpretation of the color map.

4. Pick a location on the RESULT object

in the Graphics Window with your

GD&T Callouts

The Create GD&T Callouts command provides a tool to define feature control frames (callouts) on the

CAD reference object. These callouts will be used to define geometric characteristics to control size and

form limits for individual features.

Callouts created are passed to the Evaluate GD&T Callouts command to generate visual feedback on

the form and fit of the scan data.

Click Calculate Shrink to apply the shrink

to the selected region, see Figure 176.

This will shrink the TEST data mapped to this face away from the face edges. In this example, the scan data runs beyond the edges defined by the REF object, this is due to scanning, in which sharp edge/corners are seldom captured. Instead, sharp corners/edges are often captured as rounds or fillets, causing a slight mismatch between scan data and REF data.

Compare Features

ACTIVITY: Compare Features

Objective

Generate annotations individually and automatically in the Compare Feature command. You will use an

existing inspection data set that contains features on both the TEST and REF to generate annotations. The

command will report the size and position differences between features on the TEST and REF objects.

Training File

TR-16.wrp

Open File

1. Open the file TR-16.wrp.

It is not necessary to run 3D Compare beforehand in order to use Compare Features. However, it is valid only when the Test and Reference objects are already aligned and when corresponding features are named the same.

If a RESULT object exists when entering the Compare Features command, the Compare Features Views folder is created under the RESULT object. If no RESULT object exists, the folder is created under the TEST object. Regardless of where the Compare Features Views folder is created, the analyses can be included in a Report.

If features were created using a hard probe, use Features > Edit > Name Matching to make sure features in the same location have corresponding names.

Analysis – 2D Tools

Overview

The application has a range of 2D analysis tools to extract information from cross-sections for your

inspection report. The 2D Compare command takes cross-sections through a RESULT object and displays

deviations using a whisker plot. The Section Through Object command looks similar but creates cross-

sections for 2D Dimensioning.

The Section Through Object command can be used to create cross-sections on both a REF and TEST object or on a TEST object only.

Other 2D analysis tools, 2D Twist Analysis and Blade Section Analysis, are available but are more focused

towards the turbine blade industry. All these commands create a series of 2D views that can later be

added to a report.

Figure 187


2. Select the Planar Deviation radio button in the Type roll-up group.

Planar Deviation is a whisker plot of the actual points found in the cross section. It will include all points found within the Thickness parameter.

3D Deviation is averaged with the surrounding whiskers, giving a smooth appearance of the deviation that matches the Deviation Spectrum of the RESULT object.

Set Thickness to 0.1 mm, and note the point preview at the location of the

section.

Thickness is required for points to compensate for point clouds of varying density; the value used for Thickness is divided equally to each side of the section.

Using the Max Deviation setting will exclude noisy or extraneous points that are further than the specified distance from the REF object.

3. Select the Basic radio button in the Method group.

4. Select Object Feature Plane from the

Report Generation

Overview

Reports provide an output for the inspection information/views into a format which a downstream user

can take advantage of.

After performing analysis operations and creating views, it is time to share the results with others by

generating a report. The following report formats are available:

PDF (with or without 3D PDF)

HTML

WordML

XPS

PPT

CSV

XML

A report can be customized to include or

exclude certain views, tables, or pages. With

more advanced features you can set the font

type and size for specific formats, load

special logos, and perform template

customization.

The CSV format facilitates transfer of tabular

data to a spreadsheet for further analysis.

Reports in the Task column.

End of Activity


Automation

Overview

One of the most powerful features in the application is automation. As you work on an inspection, the

application records the commands used, from feature creation and alignment, to sectioning and

reporting. At any point, a user can view the Automation Panel to see which steps have been performed

up the present point in time. At the end of the inspection, you save the file in the Geomagic (.wrp) format,

which saves not only the results of the inspection, but also all of the automation information. This means if

you wish to inspect the same part type again in the future using a new set of scan data, you simply load

in the new data set and with one button click, the same inspection criteria is applied to the new data set.

The automation feature is always on, remembering the steps taken to create the inspection reports. All of

the automation information is stored with the REF object, which is why it is recommended that some

operations, such as Section Through Object, be performed on the REF object as well as the TEST object.

Certain types of features and dimensions are not automated, due to the nature of their creation. If these

entities were created by any sort of non-repeatable on-screen selection, they will appear orange,

meaning they cannot be automated. An example would be a plane created by selecting three points

on the REF object. Green colored features and dimensions, however, can be automated and these are

necessary if an automated inspection is being created.

ACTIVITY: Generate New Report for New TEST data

Objective

Use automation tools to save time when performing multiple inspections of a part. Begin with a partially

complete inspection and finish it. Perform an automated inspection on a new set of scan data.

After completing any feature creation, alignments, analyses and report generation for a part, it is good practice to save this file as a “master file”. Now all you have to do next time is open this file, replace the scan data and generate a new report with Run Automation.

Each report that is generated using Run Automation is saved with a date/time stamp on the end of the filename.

Make sure your scan data sets have unique, descriptive names to make it easier to analyze the results later.

This is an advanced tutorial that requires you first complete several of the other tutorials in this guide.

Training File

TR-21.wrp

TR-22.wrp


Open File

1. Open TR-21.wrp.

The scan data has already been aligned to the CAD model. A RESULT object showing the deviation between the REF and TEST was also generated, along with various annotated views.

Figure 223

2. Select the REF object (CAD model) in the Model Manager Panel to make it active.

View Existing Automation

1. To view the automation command

sequences of the active REF object;

click the Automation Panel, see

Figure 224.

This sequence contains a history of all the commands that have been performed up to this point.

Figure 224 – Automation Panel


2. To see another view of this

automation, expand the REF object in

the Model Manager Panel. Expand

the Automation folder and right-

click on the only available automation

node and select Design from the

right-click menu, see Figure 225.

Figure 225

3. A dialog called the Qualify Automation Designer is opened, see Figure 226.

Not only can you review your current automation in the Designer, but you can also add additional command nodes to the workflow. Then when you play back the automation, the system will prompt you for the required inform in order to complete that command.

If intending to make changes to Automation it is good practice to Duplicate your Automation before entering the Designer.

Figure 226


4. Click the Close icon in the top right corner to close the Designer dialog.

Changes are saved automatically on exit from the Designer.

Replace Existing TEST Data and Run Automation

1. It is time now to use the automation to compare a new set of scan data to the same

CAD model using the same analysis tools.

You performed an inspection using a scan of the first production part, taken right

off the assembly line. Now you will replace that file with another point cloud, this

time a scan of the tenth production part off the assembly line, to verify the

accuracy and repeatability of your manufacturing process after ten cycles.

2. Place your cursor over the TEST object

in the Model Manager Panel and

right-click to access the right-click

menu, see Figure 227.

Select Replace from the right-click

menu.

Click Yes when you see the alert

dialog.

This command will delete the current TEST object and import a new TEST object.

Select the TR-22.wrp in the

Import Files dialog.

Click Open.

A scan of the same part but a different manufactured date is imported into the session and set as the TEST object. You are now ready to inspect this new data with Automation.

Figure 227

Auto Report

1. Make the REF object active.

Now you will test the full capabilities of the automation as you use the application to perform the inspection analysis on its own.

2. Click Automation > Automation > Run Automation.

The Automation will automatically run.

If there are more than one Automation nodes in the Model Manager Panel under the REF object; the Automation that is currently set to Active will be the Automation that is run.

When report is finished running; you will have a second report that can be found in the Report folder specified in the Options dialog (CTRL+X).

Appendix III – Additional Activities

Average Polygons

The Average Polygon Object command enables the user to create a nominal polygon object from

multiple polygons.

ACTIVITY: Average Polygon Object

Objective

Create a new polygon object that is the average of two or more scanned parts.

Training File

TR-25.wrp

Open File

1. Open the existing file TR-25.wrp.

This file contains several polygon objects, each with imperfections that will be averaged into a nominal polygon model.

Average Polygon Objects

1. Highlight the name of one polygon objects in the

Model Manager Panel, and then CTRL+LMB

click the names of the other five objects.

See that the six selected polygon objects are superimposed in the Graphics Window.

Best Fit alignment was used to align each of the scanned models to each other.

Figure 231

2. Click Polygons > Combine > Average.

3. In the Average Polygon Objects dialog, change the Name of the object to be

created to Nominal Object.

4. Expand the Advanced Options roll-up group.

5. In the Reference drop-down, select Minimum Deviation which automatically

selects the original that is the most similar to the average of all.

Reference - specifies which of several originals is considered to be the reference object. Deviations of the other object(s) will be calculated with respect to the reference object.

6. In the Parameters group, do not change the defaults.

7. Click Apply to generate the averaged object named Nominal Object.


8. Expand the Deviations roll-up group. This will

help the user determine whether a single original

polygon object has had a bad influence on the

Nominal Object and should be discarded.

Initially, all original polygon object names are simultaneously selected in the list. When all original polygon object names are selected in the list, the Graphics Window is a comparison of the Nominal Object to the average of all originals. There should be little difference.

Figure 232

9. Select one of the original polygon names in the list. The Graphics Window will

display a comparison of this one original to Nominal Object. If the Graphics

Window reports high deviation between this original and the Nominal Object, the

original is a candidate for being discarded.

Repeat this for each of the original polygon objects.

10. Now select multiple original polygon names from the list using CTRL+LMB. In this

case, the Graphics Window reports the deviation between the average of selected

originals and the Nominal Object.

It is possible that a discard candidate should be “reinstated” because it balances another original that deviates in the opposite direction.

If one or more of the original polygon objects are still considered to be “bad”, you would terminate the command and re-start it without selecting the bad polygon object(s) in the Model Manager Panel. In this exercise, all originals are considered to be good.

11. Click OK to exit the dialog, upon exit, your new Nominal Object will be added to the
